drm/amdgpu: update the domain flags for dumb buffer creation

Browse Source 
After switching to generic framebuffer framework, we rely on the
->dumb_create routine for frame buffer creation. However, the
different domain flags used are not optimal. Add the contiguous
flag to directly allocate the scanout BO as one linear buffer.

Fixes: 087451f372 ("drm/amdgpu: use generic fb helpers instead of setting up AMD own's.")
